Flash uploader gets unresponsive when uploading multiple files.

I'm uploading ± 20 files of ± 0,5 mb. Sometimes you don't get the error message.

I don't think the cause of that error message HAS to be from a for or while
loop...

The message is directly related (I believe) to the % of the CPU required in
combination with the duration of use.

I have also seen that problem when forgetting to put a stop() in appropriate
places, causing a frames code to be called at the FPS rate.

By the way, how big are the files being uploaded?
